To @ZZ @07m/a it may concern Re it known that We, LEONARD li. Birnns and Geenen G. HUNTER, citizens of the United States, residing at Valentine, in the county ot Cherry and State oila Nebraska, hare invented certain nevv and useful lmprovements in Soldering-Irons; and We do hereby declare the following to be a full, clear, and exact description ot the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

rlllhis invention is a soldering iron or cop-- per and has for its object to provide a burner for effecting a more complete combustion of tuel `with a consequent better heating eli'ect by 'the use of any suitable gas under pressure.

A further purpose oi' this invention is to provide the operator with irons ot various sizes and shapes, suitably proportioned to the Work in hand, that may readily be substituted for the one in use on the burner Without danger to the hands oi the operator from the heated iron.

Another object is to provide a plurality ot mining chambers to increase the heating c( pacity with a consequent saving in fuel.

llith these ends in view, the invention consists of an interchangeable copper or iron having a combustion and mixing chamber', suitable connecting means tor engaging a handle ot non-conducting material, a burner provided with a minin chamber and adapted for engagement with a plurality of dit ierent irons, said burner cooperating with said handle, and means for conveying gas to the burner.

@ne embodiment of the invention is shown in the accompanying drawings, in Whichlligure l is a side view. llig. Q is a transverse section on the line 2N2 of Fig. l.

is an end view et the iron 'lhe soldering iron or copper fr is provided. with a plurality of transverse ports ont varying diameters B, connecting with the mixing and combustion chamber C, to carry oil'1 the products ot combustion, and supplying additional air to be heated and consumed. These apertures decrease in size as they approach the Working end ot' the iron. By making these ports ol3 various sizes, it prevents the flame from being Specification ot Letters Patent,

chilled and its temperature lowered as Well as preventing an undue chilling of the iron, by the introduction of too much cold air, the smaller ports retaining the heated air and allowing it to escape slowly and gradually that it may give up its heat units, Without creating a draft. rllhe Walls are heated by this method by conduction convection and radiation, and to a great extent the eddy currents, produced by the entering cold air to the mixing and combustion chamber, are prevented, enabling the iron to be more thoroughly heated at the point thereof. At the inner end ot the iron A is an aperture D, substantially centrally located which at its outer end is preferably cone-shaped and which communicates with the mixing and combustion chamber C. Arranged around, and adjacent to, aperture D are air inlet ports E. The air inlet ports E terminate within the chamber C at a point beyond the seat of the burner nozzle l?, which is preferably of truncated cone shape and adapted to engage with a seat Within the aperture l), making a substantially air and gas tight joint. The air ports E admit air to the flame at a point Where it produces the maXi mum amount of heat and consequently using less gas. These ports lil, communicating With the chamber C, are preferably angularly displaced With reference to the longitudinal axis of the iron A, so that the entering air has the same relative direction ot flow as the gas.

rlhe iron fr is provided with an arm or arms G, said arms being suitably connected in a permanent manner to the iron A, and to the tapered sleeve H. The sleeve l-l may be rigidly connected With the handle l, by any suitable means. One means is shown by the screw (l, to prevent the sleeve H, carrying the iron A, from revolving or moving during the operation of soldering, and to keep the burner nozzle F in engagement with its seat D. rlhe employment oii such means allows interchangeability ot diiierent sizes of irons, whereby the tool may be adapted to light or heavy Work, as the occasion may require, and is :tor all purposes a solidly handled soldering iron.

rlhe sleeve l-l may be made of any suitable material.

The handle l is, preferably, made of suit able material, such as wood, having centrally located, through its longitudinal axis,

a hole K, adapted to receive a gas tight tube L, which is provided with suitable means at its outer end for connection with a gas supply, to convey gas to the mixing chamber 'i' in the member M of the burner, located upon the inner end thereof.

The burner comprises a mixing chamber r in the member M, preferably of larger diameter than the gas supply tube L. This burner is preferably secured to the tube L by a suitable coupling S. The member M is shoivn in Fig. 3 provided With a threaded end m and with an inner reduced portion a forming a small nozzle at g, whereby gas under pressure is admitted to a chamber r into which leads the inclined ports O. rThe air ports O are so positioned that the incoming gas draws air through them in the same relative direction as the gas floiv, thereby producing a more thorough mixture, consequently using the gas with greater economy and generating greater heat in the Haine.

Projecting from the member M is a stem P, carrying at its outer end the substantially truncated cone-shaped burner nozzle F, which engages with its seat D in the iron A. The nozzle F is provided with a centrally disposed opening which communicates directly with the mixing chamber r ot the burner, and also with the mixing and combustion chamber C. 1t Will be observed that a continuous passage is provided from the gas supply tube to the combustion chamber ot the iron. Upon the gas supply tube L may be located any suitable means, such as a stop cock (not shown) for controlling the supply ot gas.

In operation, gas is admitted under pressure to the outer end of tube L, iiowing thence to the mixing chamber of the burner Where it comes into contact with the air. The pressure of the gas draws air through the air inlet ports, and mixes it with the gas. The mixture then passes through the stem P and through tie opening in the burner nozzle into the mixing and combustion chamber C. J ust beyond this nozzle F terminate additional air inlet ports E. rl`he air inlet ports supply additional air to the flame at its point of combustion and tend to produce an intense blue flame. he admission of air at the lower part of the flame to be gently blown over the combustion cone in the same relative direction, produces a flame of intense hea-t with neither oxidation nor deoxidation. That is, the composition of the flame will be one that creates the greatest amount of heat, thereby materially changing the character and quality of the flame The products of combustion are carried 0E by the transverse ports which communicate with the mixing and combustion chamber, thereby providing more complete combustion.

It is obvious that the invention is not limited to the precise construction shown in the drawings, as various modifications and alterations may be made therein by one skilled in the art Within the scope of the appended claims. o
